I looked into the logs in %temp% (thanks to @ganeshr for pointing me to the right location to the logs) and I found that errot:

ERROR: The type initializer for 'System.Windows.Media.FontFamily' threw an exception.

I searched the internet and found that it's a WPF font issue, this link helped me understanding where is the issue came from: http://stackoverflow.com/questions/9066930/wpf-window-crashes-on-startup-or-it-starts-but-hangs-and-does-not-render-conten

I did some font clean up, removed unused fonts for me and I think because I had a lot of update for the default installer font: Segeo UI this cause the error. I removed the old updates and finally the installer opens.

Thanks for you your all support.

EDIT: BTW I had to restart the following services and not sure if this is relevant/fixes the issue:

• Windows Font Cache Service
• Windows Presentation Foundation Font Cache 3.0.0.0
